I've had a pair of these speakers for about 4.5 years mounted on my West facing deck under the eve. No direct rain, few hours of direct sunlight. Well about a month ago one blew. Took the cover off and you could clear see where it had cracked around the speaker surround. Took the cover off the other one and it had a small crack as well. Got out the receipt and called Jamo. Long story short a few weeks later a brand new set of I/O 8A2's arrived. I was extremely pleased that they honored their warranty (5 years) as I expected mine to be refurbished or another refurbished set sent in replacement. Did I mention these speakers sound GREAT? I wonder why the surrounds on both cracked? Any ideas?
